PREFACE
Theprovisionofearthquakeresistant structuresandfacilitiesisoneofthemain concerns of
Civil and Earthquake Engineering Profession. As such, the main objective of seismic
instrumentation program for civil engineering structural systems is to improve our
understanding of the behavior and potential for damage of structures under the dynamic
loads ofearthquakes. As a result of this understanding, design and construction practices
can be modified so that future earthquake damage is minimized. Therefore, there are
significantimplications in(a)hazard reduction,(b)improvementofcodes,(c)identification
ofseismic responsecharacteristics ofstructuralsystemthat maybeusedindeterminationof
strategies for improvement oftheir performances.
There are twomain approaches toevaluateseismicbehaviorand performance ofstructural
systems. One requires a laboratory in which subsystems,components, or (if the facility is
large enough) prototypes or large, scaled models of complete systems are tested under
static, quasi-static,ordynamic loading.Thisapproachdoesnotnecessarilydemand atime
dependent testing scheme, such as a shaking table or hydraulically powered and
electronically controlled loading systems; however, testing of structural systems under
controlled simulated environments is desirable. Since the early 1950's such laboratory
research hasincreasedbothinquantityandquality,withengineeringcollegesintheUnited
States and private and governmental laboratories in Japan playing a key role. Laboratory
testing has also contributed substantially to our understanding ofdynamic soil properties
and the interaction phenomenon betweenthesoiland structure.
The second approach toevaluate behavior and performance ofstructural systems isto use
the natural laboratory of the Earth, byobservingand studying damage to structures from
earthquakes.By determining why specificdesigns lack earthquake resistance and then by
using extensive laboratory testing of modified designs, significant progress in improved
designs can be achieved. The validity ofthe modelsofanalysis used in the assessment of
the earthquake behavior of structures can only be checked by way of comparison with
relevant field observations. For such design studies, a natural laboratory would be a
seismically prone area that offers a variety of structural systems. Integral to the "natural
laboratory" approach is the advance instrumentation of selected structures so that their
responses can be recorded during future earthquakes. Thus, it is essential that integrated
arrays of instrumentation be planned and installed to assess thoroughly the relation of
ground motion that starts at a source and is transmitted through various soils to a
substructure and finally to a superstructure.The direction for seismologists and engineers
working together is clear; to develop integrated networks which measure the seismic
source,thetransmittal ofground motion,andthestructural responseprocesses.

Strongmotion instrumentationofstructures hasbeenutilized since 1940's.Throughoutthe
world, strong motion instrumentation networks have been installed on buildings,
monumental and historic structures, bridges, dams, tunnels, pipelines and power plants.
Recent strong earthquakes, Mexico City (1985), Loma Prieta (1989), Landers (1992),
Northridge(1994), and Kobe(1995) haveyieldedawealth ofstructural response data from
instrumented structures. These data have contributed tothe evolution and enhancement of
seismic analysis and design methodologies,seismicbuildingcodesand practices.In the last
decade, there have been significant advances in the development of digital seismic
monitoringsystems, data retrieval, processing, storage and dissemination capabilities.The
new strong motion recording instruments with advanced technologies allow for: High
dynamic range (24-bit with micro-g acceleration resolution); Large memory capacity (few
hours); On-board real-time processing of data and; Extensive communication options.
These developments have reducedthe initial andthemaintenancecostofthestrong motion
instrumentationand pavedthe path fortheir increased utilization.
Recent changes in instrumentation technology and the need by public officials as well as
the public for early damage assessment and disaster response haveadded a newdimension
to these efforts. The ideal venue for obtaining strong-motion response data is now being
considered in terms of real-time acquisition and processing. Monitoring the dynamic
behaviorof structures for quick damage assessment and early warning are new and active
areas of research. Although still in development stage, several developments in the
structuralhealth monitoringtechnologyisslowlytaking placewithin severalstrong-motion
programs, for research and on "as needed and feasiblebasis".Developments for real-time
(or near-real-time) serviceability assessment for important lifelines (bridges, dams and
pipelines) are also being implemented.
It should be noted that, most of the existing strong motion instrumentation on civil
engineering structures are installed and operated as federal, state, university, industry or
private applications. In many cases, there is very little or no coordination between them.
Some of them are managed as closed systems. Limited co-operation programs and data
exchange arrangements hinder difficulties and delays in acquisition ofstrong motion and
structural data, even within the same country,byengineers and researchers external to the
system. As a result of this lack of coordination and information, the strong-motion data
obtained from the instrumented structures are not fully utilized by the engineering
profession.
In the on-going globalization movement there exist a strong desire and need for co
operation in strong motion instrumentation programs and enhanced data exchange
programs. Similarly, there exist a strong needtoinform practicingengineerson the useof
existingstrong-motiondata and toimprovetheworldwideaccessibility ofdata.The NATO
ARW held and this publication isan attempt toanswer this needthrough dissemination of
the developmentson strong motion instrumentationofcivilengineeringstructures.
The editors wish to express their deep appreciation to NATO, other sponsoring
organizations and several individuals whose personal efforts made the workshop and,
